Description

500kV pull wire tower pull wire rod lower handle nut removal socket wrench

technical field

The utility model relates to a tool for dismantling nuts of cable towers, in particular to a special socket wrench used for dismantling the nuts under the cable rods of cable towers of 500kV transmission lines.

Background technique

During the operation of the 500kV AC-DC transmission line, the guy tower is often affected by external force damage, operating climate and other conditions, and the guy is prone to tension relaxation, broken strands, and corrosion of hardware. At present, when the traditional method of working with (stopping) electricity is used to replace or adjust a stay wire, the operation steps are more complicated, taking 8-9 hours and involving 9-10 people. When disassembling or tightening the nut under the pull rod, due to the small gap between the nut under the pull rod and the edge of the anti-theft cover, it is impossible to use a fixed wrench to disassemble or fasten the nut, although the common socket wrench The above problems can be solved, but because the part where the lower handle nut is screwed into the bolt is longer, the sleeve of the ordinary socket wrench cannot pass through the bolt, so it is impossible to disassemble or fasten the lower handle nut, so it is necessary to provide The utility model relates to a socket wrench which is specially used for removing the nut under the pull wire rod of the pull wire tower.

Utility model content

The utility model provides a simple structure and easy operation in order to overcome the shortage that the common socket wrench cannot pass through the bolt to disassemble or fasten the nut during the operation process of changing the pull wire, adjusting the tension of the pull wire, UT wire clamp, and duplex plate. A convenient socket wrench for dismantling the nut under the pull wire rod.

For realizing above object, the technical scheme that the utility model adopts is:

A socket wrench for dismantling the nut of a 500kV cable tower cable rod, including a socket, a rotating head, and a handle connected to the side of the rotating head. The top of the sleeve has a limit boss, and the rotating head is provided with a longitudinal A through limit card slot, the limit boss is clamped in the limit card slot, and the sleeve is also provided with a bolt passing hole longitudinally penetrating the sleeve. Since the sleeve is provided with a through hole for the bolt to pass through, and the rotating head is also a through hole structure, the socket wrench can pass through the bolt during use, which solves the problem that the ordinary socket wrench cannot pass through the bolt to disassemble or fasten the nut. question.

Further, the side of the rotating head is provided with an externally threaded joint, and one end of the handle is provided with an internally threaded hole matching the externally threaded joint. The use of thread structure can prevent slipping during operation.

Further, the handle is made of aluminum alloy. The aluminum alloy material is light in weight, which can reduce the physical loss of operators.

The socket wrench of the utility model can pass through the bolt during use, which solves the problem that the ordinary socket wrench cannot pass through the bolt to disassemble or disassemble the nut during the operation process of changing the pull wire, adjusting the tension of the pull wire, UT wire clamp, and duplex plate. The problem of fastening has the advantages of simple structure, convenient operation, sturdy and durable, and light weight, which reduces the physical loss of operators and improves work efficiency

detailed description

The content of the present utility model will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

Example:

Please refer to Fig. 1 and Fig. 2, a kind of 500kV cable tower cable rod nut removal sleeve wrench, including a sleeve 1, a rotating head 2 and a handle 3 connected to the side of the rotating head 2, the sleeve 1 The top of the top has a limit boss 4, the rotating head 2 is provided with a limit card slot 5 through the longitudinal direction, the limit card 4 is set in the limit card slot 5, and the sleeve 1 is also A bolt passing hole 6 is provided longitudinally through the sleeve 1 .

Wherein the shape of the limit boss 4 and the limit card groove 5 is a regular quadrilateral, the limit card groove 5 blocks the limit boss 4, so that the sleeve 1 can be driven to rotate together with the rotary head 2, and the bottom of the sleeve 1 is an inner Hexagonal hollow structure. The side of the rotating head 2 is provided with an externally threaded joint 7, and one end of the handle 3 connected to the rotating head 2 is provided with an internally threaded hole 8 matching the externally threaded joint 7, wherein the handle 3 is made of aluminum alloy.

When in use, fix the sleeve 1 through the bolts and nuts, tighten the rotating head 2 on the handle 3, use the limiting slot 5 of the rotating head 2 to clamp the limiting boss 4 of the sleeve 1, and turn it counterclockwise The handle 3 drives the sleeve 1 to remove the nut, and turns the handle 3 clockwise to drive the sleeve 1 to fasten the nut.

The above detailed description is a specific description of the feasible embodiment of the utility model. This embodiment is not used to limit the scope of protection of the utility model. Any equivalent implementation or change that does not deviate from the utility model should be included in this case within the scope of protection.
